I think I figured something out. I used the table view's method for
tableViewSelectionDidChange and I could set the panel's previewed item as that
changed. It works but might not be optimal.
Thanks for any replies.

Subject: Quicklook and changing previewed image from table
I'm building an app that has a table view which holds paths of images. I have
enabled quicklook so I can press space bar and the preview window will show up.
I can view 1 image and close the preview and show another image preview. But if
I have the quicklook preview panel displayed, it won't update the image
displayed, when I use the arrow key to scroll up/down in the table. I am pretty
sure I need to call
[[QLPreviewPanel sharedPreviewPanel] refreshCurrentPreviewItem];
//or the name of the panel instance itself
But where do I do that?
I have a tableView class that intercepts keystrokes to call the panel toggle on
spacebar, and it will change the table selection too.
//inside of tableView subclass
- (void)keyDown:(NSEvent *)theEvent
{
NSString* key = [theEvent charactersIgnoringModifiers];
if([key isEqual:@" "]) {
[[[self window] windowController] togglePreviewPanel];
} else {
[super keyDown:theEvent];
}
}
I tried putting the refresh... call inside of the else block, but that didn't
do anything. Would something go in my tableView, or the WindowController (which
is where the panel is created)?
Thanks,
Chris
